Create Third-Party Integrations with Platform Events

To trigger notifications using an external, or third-party, system, subscribe to Salesforce platform events.

You can subscribe to browser events or processes running on the Salesforce platform using Streaming API, which is built on the Bayeux protocol. Subscribe to events upon order confirmation or for intermediate checkout stages.

• Order confirmation—When an OrderSummary sObject is created successfully, Salesforce triggers the OrderSummaryCreatedEvent. Applications can subscribe to this platform event and send notifications from external systems to Salesforce.
• Intermediate checkout stages—Create a custom platform event, such as the event described in Create a Platform Event for Checkout Notifications. Applications can subscribe to your platform event and send notifications from systems external to Salesforce.
